Dlium Walur (Amorphophallus variabilis)
Leaves with 1-2 strands and stalk 10-100 cm long. The leaf blade is 15-100 cm long, has three parts, each part is further divided in elongated or lanceolate with a tapered tip or tail-like.

Flowers appear when the vegetative organs wither and grow in an independent cob. Stalks long and slender for 2-100 cm and often with rough pimples. Base with some protective leaves.

The female flowers sit starting at the base and are green. The male flowers are yellow, twice as long as the female part, the sterile part is twice as long as the female part with the male, often grooved or flattened and yellow or purple in color.

The flower is triangular elongated with a pointed tip. The ear is 6-46 cm long and 1-5 cm wide. The top of the cob is elongated. The fruit is crowded, red-orange and has 1-2 seeds.

Tubers are yellow and itchy in the mouth when eaten. The tubers produce shoots that can be separated. In times of famine, the tubers are sliced into small pieces and then boiled for eating. The tubers are also grated or ground and cooked in banana leaves.

Leaves, petioles, fruit and fruit cobs are cooked as vegetables. Leaves as food for fish in ponds. Tubers are rich in mannan, a carbohydrate that can be made into konnyaku.

Most scientists and science activists have agreed that god is nonsense, delusional and cannot be accommodated in the theory of evolution. This opinion can be understood methodologically and I agree with the sentences. But so many behaviors are very real and occur in the field.

I feel something is missing in the view of naturalists and Darwinians. There are short moments that are missed in analyzes in the timeline of human evolution. These lit…

Javanese grasshopper (Valanga nigricornis)

Wooden grasshoppers or wooden walang or Javanese grasshopper (Valanga nigricornis) are grasshopper species in Acrididae and have around 18 subspecies, most of which are endemic to various island groups in Indonesia. This insect has a very broad sexual dimorphism where males have a length of 45-55 millimeters and females 15-75 mm.

V. nigricornis is yellowish brown or yellowish or green with bluish black marks. The back wing is rose red when flying. The nymphs are pale green and dark. They live in forests, bushes and really like the leaves of the giant sensitive plant (Mimosa diplotricha) and giant sensitive tree (Mimosa pigra).

Javanese grasshopper has one generation every year where four eggs are placed on moist soil in forest clearing. The eggs are not active throughout the dry season and it takes six to eight months to hatch.

The eggs hatch into nymphs and pass seven instar stages before becoming winged adults. Wood grasshoppers are solitary insects and do not form flocks, but outbre…
